Designed for astrophotography but also great for observation, the FF107 APO Astronomical Telescope from ZWO features a quadruplet air-spaced apochromatic lens system that eliminates the need to use a separate field flattener. The quad APO with two extra-low dispersion elements also dramatically reduces chromatic aberration and eliminates the need to calculate back focus distance—just attach your camera with one of the four included adapters and you're ready for imaging. The f/7.0 focal ratio and 749mm focal length lend themselves to both planetary and deep-sky photography. An optional diagonal and eyepieces are required for visual use.
Optical Tube Assembly
- Large 130mm aperture makes it ideal for making detailed observations of the moon and planets and viewing deep-sky objects like binary stars, clusters, and galaxies
- f/7.0 focal ratio and 749mm focal length allow for both deep-sky and planetary imaging
- Quadruplet air-spaced apochromatic refractor design with two ED elements produces rich views with minimal chromatic aberration
- Quad APO is self-flattening, eliminating the need for a separate field flattener
- Supports 44mm image circle for full-frame cameras
- Fine spot diagram with tiny distortion of peripheral stars and under-3µ central RMS radius
Focuser
- Sturdy 3" rack-and-pinion design can easily carry larger and heavier eyepieces, accessories like Barlows and focal reducers, and imaging systems
- 360° rotator with scales and finder base
- 10:1 fine adjustment ratio
Use and Handling
- Anodized red handle and tube ring assembly, can be detached and reinstalled in seconds
- Handle has M6 screw holes for attaching accessories
- M86, M68, M54, and M48 camera adapters
